Time Evolution of the Stability and Oxygen Reduction Reaction Activity of PtCu/C Nanoparticles

Crystalline Cu3Pt nanoparticles supported on graphitized carbon are synthesized by using a modified sol–gel method, and subsequent thermal annealing leads to alloying of Pt with Cu and formation of a partially ordered Pm${\bar 3}$m structure. Electrochemical dealloying under potentiodynamic conditio...
